When Ronald Reagan died in 2004 after a decade-long battle with Alzheimer's,pundits across America repeated the conventional wisdom about dementia. The former president was only a "shell"; and "shadow"; of himself in his later years,they said, and his physical passing was a mere formality, the symbolic loss of a man who had vanished long ago. Those comments always bothered me, but I never fully understood why until two weeks ago, when I lost my father, Thomas Patrick Carroll Sr., to the same disease.
